formic acid (HCOOH)
Also known as methanoic acid (its systematic name), a colorless,
corrosive, pungent liquid, which is the simplest and strongest carboxylic
acid. Formic acid occurs in the stings of ants
and nettles. Formic acid is made (via sodium formate) by heating sodium
hydroxide with carbon monoxide under pressure. It is used in tanning, as
a latex coagulant, in electroplating, and to reduce dyes.
The aldehyde derivative of formic acid is methanal.
